P2P VPNs allow you to connect two or more hosts together and do some stuff like play games or test out services just like you were on one real physical local network (LAN). Even when you are on different continents.

Context

You want to run an app on Azure appService linux (here a nodeJS app) with a simple SQLite database.

Your have read https://www.sqlite.org/whentouse.html and your app requirements are simple enough (no big concurrency, no horizontal scaling) to consider SQLite, and you don't need yet more sophisticated solutions like PostgreSQL.

You use a NodeJS based app with the Prisma ORM.

This example pulls together various examples of work with trees in D3.js.

The panning functionality can certainly be improved in my opinion and I would be thrilled to see better solutions contributed.

One can do all manner of housekeeping or server related calls on the drop event to manage a remote tree dataset for example.

Dragging can be performed on any node other than root (flare). Dropping can be done on any node.

Panning can either be done by dragging an empty part of the SVG around or dragging a node towards an edge.

Pro-tip: look through the github diff between the previous release to see what's changed. The commit titles should give an outline of what's happened.

• List out, as concretely as possible, any steps users have to take when they upgrade beyond just dumping the dependency.
• Write pseudocode that highlights what code should change and how.

With this wiki2html.sh bash script and pandoc program, you can convert markdown to html.

Usage: In the vim list section of the .vimrcfile, include options:

let g:vimwiki_list = [{'path': ‘your_wiki_place',
  \ 'path_html': ‘wiki_html_location’,
  \ 'syntax': 'markdown',
 \ 'ext': '.md',

URL: https://www.reddit.com/r/ProgrammingLanguages/comments/up206c/stack_machines_for_compilers/i8ikupw/ Summary: stack-based vs register-based in general.

There are a wide variety of machines that can be described as "stack-based" or "register-based", but not all of them are practical. And there are a lot of other decisions that affect that practicality (do variables have names or only address/indexes? fixed-width or variable-width instructions? are you interpreting the bytecode (and if so, are you using machine stack frames?) or turning it into machine code? how many registers are there, and how many are special? how do you represent multiple types of variable? how many scopes are there(various kinds of global, local, member, ...)? how much effort/complexity can you afford to put into your machine? etc.)
